Active Dry Yeast
Description
Active dry yeast is a type of dormant yeast used widely in baking, particularly in the preparation of breads, rolls, and other leavened bakery products. It consists of coarse, oblong granules that are reactivated by soaking in warm water (between 105°F and 110°F or approximately 40°C to 43°C) prior to mixing with flour. This activation process is known as 'proofing' the yeast. Active dry yeast helps dough to rise by producing carbon dioxide gas as it ferments the sugars present in flour. This leavening agent is available in small packets or jars and should be stored in a cool, dry place to maintain its freshness and potency. It is a staple in kitchens across the world, from North America to Europe to Asia.
Common uses
Active dry yeast is most commonly used in the preparation of baked goods such as bread, pizza dough, rolls, and pastries. It is also used in the brewing of beer and wine, as well as in the production of ethanol for fuel. In addition, active dry yeast serves as a nutritional supplement due to its high content of B-complex vitamins and essential nutrients.
